IMO its not worth it, its only Flash 6 so you can't use it for youtube or google video

I tried out the demo today after seeing the game on On The Spot (gamespot weekly video show thingy) and it looks to be one of the best titles coming up on the PSP, very original idea that plays great. It's nice to see the PSP get downloadable demos too, hopefully this continues in the future.
